Study Notes
Economic Growth
- Defined as an increase in real GDP over time or real GDP per capita.
- Example: If real GDP rises from $200 billion to $210 billion, the growth rate is 5%.
- Rule of 70: Estimated years to double real GDP = 70 divided by the annual growth percentage.
The Business Cycle
- Describes fluctuations in economic activity marked by alternating expansions and contractions.
- Declines in real GDP lead to significant rises in unemployment.
- Rapid economic growth can coincide with high inflation.
Phases of the Business Cycle
- Peak: Maximum business activity; near full employment and productivity; likely price level increases.
- Recession: Period of decreased output, income, and employment; widespread contraction in business activity; likely price level decreases.
- Trough: Lowest levels of output and employment; can be brief or prolonged.
- Recovery: Rising output and employment towards full employment; price levels may begin to rise before reaching full capacity.
Unemployment
- The labor force includes individuals able and willing to work, comprising both employed and unemployed individuals actively seeking work.
-
BLS Categories:
- Employed: Paid employees, self-employed, unpaid family workers.
- Unemployed: Individuals not working but available and seeking employment within the last four weeks.
- Not in the Labor Force: Those not qualifying as employed or unemployed (e.g., students, homemakers, retirees).
Labor Force Statistics Calculation
- Labor Force: Total workers = Employed + Unemployed = 145.9 million + 8.5 million = 154.4 million.
- Unemployment Rate (u-rate): Calculated as (Unemployed/Labor Force) x 100 = (8.5/154.4) x 100 = 5.5%.
- Adult Population: Total population = Labor Force + Not in Labor Force = 154.4 million + 79.2 million = 233.6 million.
- Labor Force Participation Rate: (Labor Force/Population) x 100 = (154.4/233.6) x 100 = 66.1%.
Unemployment Rate Formula
- The unemployment rate represents the percentage of the labor force that is unemployed:
- Unemployment Rate = (Unemployed / Labor Force) x 100.
